The growth in mission critical, high bandwidth applications, such as storage and voice in the work place, has made network performance and security essential. With the introduction of 802.11n, wireless technology is no longer lagging behind wired performance. The Linksys Business Series WRVS4400N wireless router answers the growing business' need for access, speed and security. The WRVS4400N implements draft 802.11n (Wireless-N) technology with a Virtual Private Network (VPN) Router that features a built-in 4-port full-duplex 10/100/1000 Gigabit Ethernet switch. By overlaying the signals of multiple radios, Wireless-N's "Multiple In, Multiple Out" (MIMO) technology multiplies the effective data rate resulting in greater throughput and coverage over 802.11g. Unlike ordinary wireless networking technologies that are confused by signal reflections, MIMO actually uses these reflections to increase the range and reduce "dead spots" in the wireless coverage area. At the same time, Wireless-N is backwards compatible with Wireless-B and -G devices.
